This invention relates" to a combined road builder, ditcher and brush breaker, as described in' the present specification and illustrated in the accompanying drawingwhich forms part of the same.

This invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are t o-build an efficient road builder, ditcher and brush breaker,of light and strong construction; to operate the same at a minimum amount of 5 power; to adjust the cut to. different depths and widths; to tilt the plow when desired; and generally, to obtain other objects and advantages as will readily appear by reading the specification and claims following.

In the drawings: Figure 1 is a plan view ofvthe device; Figure 2 is a perspective viewof the same; Figure 3 is a fragmentary perspective view showing means of raising or-lowering the wheel 7 of the front truck. Like numerals of reference indicate corresponding parts in the various figures. Referring to the drawings, the plowing unit 10 is drawn from the front trucklOB 39 of which 7 is the land wheel and 8 the furrow wheel. The plow unit consists of a mould-board 1 attached to the standard 1* which in turn is secured to the plow beam 2, the plow beam being detachably attached to the cross beam 4 of the front truck 10B with bolts as at 5 and6. The mould-board is made substantially as shown, that is, so formed as to raise the earth or dirt onto the endless belt 26 without turning the dirt over as is done in the present day practice. It will be evident that by not turning the dirt over, the traction'required to 'operate thisditching device will be decreased as compared with that required for'operating similar ditchers wherein the dirt is turned over the mould-board. v

Members 2 and 2 formed substantially as shown are preferably provided for purposes of making the plow unit as rigid and strong as possible. The mould-board is provided 1927. Serial N0. 132,458.

with a cutting share 22 which has a knife coulter 23 braced to the plow beam by a member 24. At the top of the coulter is a curved offset 25 for the purpose of turning the grass, root clumps, etc., toward the furrow, thus preventing or minimizing the plow beam andcoulter.

clogging between An endless belt 26 is trained over the rollers 38, 39 and 40 journalled in the conveyer frame members 36, the belt being driven by the roller 40 which is the driving roller.

' One end of the conveyer frame rigidly car ries the members 37 converging to meet for purposes of hinging on the plow unit; the other end of the conveyer frame is rigidly secured to the beam or member 41 and to the brackets 43 and 43 which in turn are secured to the beams 42 of the longitudinal truck The rear wheel 28 rotates in the arm or bracket 44 mounted on the upright shaft 34 rotatably mounted between the beams 42 and the beam 41.

On the shaft of the roller 40 is rigidly mounted a bevel gear 35 meshing with double-faced gear 33 'loose on the shaft the 34 meshing with the gear 33 is a bevel gear 32 rigid on the shaft 31 journalled in the swiveled bracket 44; on one end of the shaft 31 is a bevel gear 30 meshing with the crown gear 29 rigid on the rear wheel 28. Thus,

the belt is driven from'the rotation of the wheel 28, or motion of the device, irrespective of the angular position of this wheel with respect to the axis of the truck 43B.

The forward end of the truck 43B is supported by another wheel 48 j ournalled in the bracket 47 swivelled on the shaft which is mounted between the beams 42 and brackets formly or to rise at either end.

The front truck is made to rise and lower' uniformly, or to tilt at either end, with wheels 7 and 8 free to turn sideways.

the

The wheel 7 is journalled on the axle 75, the upper part of which is threaded as at 21; the axle is made square in cross section and fits in the correspondingly square bored sleeve 7 6 which has the crank 61; the sleeve is mounted between the angle member a and the inclined member 77 which is secured to said angle member l; a gear '17 is threaded on the screw portion 21 of the axle between the sleeve 76 and member 7 7 (see Figure '3'). Any rotation of -the gear 17 will raise or lower the axle, moving the wheel 7 and therefore raising or lowering one endof the beam 4:.

From the top of the axle 75 extends horizontally a plate 79 through which verticallyarranged guide rods 67 and 68 extend, these rods being secured at the bottom end in a bracket or extension 80, from the sleeve 76'; a vertically-arranged shaft 64 extends through the said plate 79 and bracket 80,the lower end of the said shaft rigidly carrying a bevel gear '65 meshing with a. crown gear 66 centered and rigid on the wheel 7. As the bracket 80 is rigid with the sleeve '7 6 through which slides the axle 75, the guide rods 67 and 68and the shaft -64.- will always hear the same parallel relation to one another irrespective of the horizontal or vertical position of the wheel'7; similarly, the gear will always be in meshing engagement with the crown gear 66.

.A gear box 14 is slidably mounted on the guide rods 67 and 68 and is raised and lowered by a clamp lever 10 working in the quadrant 11 and releasably locked in various positions by the usual clamp handle 13. In the gear box are the gears 15, 16 and 18, the gear 15 being slidably mounted on the shaft 64 and rotating therewith, and the gears 16 and 18 being rigidly mounted on a common shaft so as to rotate together. Thegears 15 and 16 are always in meshing engagement, and the gears 15 and 18 being positioned to alternatively engage with the gear 17 on the axle 4:. When the gear 17 isin mesh with the gear 15, the axle will, let us say, be raised, whereas whenthe said gear 17 is in mesh with the gear 18, the axle will be lowered. Thus the wheel 7 can be either raised or lowered according as to whether the gear 17 is in mesh with the gear 15 or with the gear 18.

The wheel 8 is journalled on the axle 82 the upper end of which is threaded as at 19 on which turns the hand wheel 20 from which extends downwardly the hub portion 83, the

hub being in turn journalled in the beam 4; as the hub and the wheel 20 form one unit, the wheel is free to rotate but constrained against vertical movement relatively to the beam 4-, and the wheel 8 can be moved up and down according to the direction in which the hand wheel 20 is rotated. 7

Both wheels 7 and 8 are retained in a fixed relative position by pivoting a spacing rod 63 between. the crank ends 61 and 62'; the

crank 62 is held under the cross beam 4c and adapted to turn with the axle 82 but allow same to slide up and down therethrough.

The traction power is applied to the rod or beam 63 to cause the wheels 7 and 8 to turn in the direction of the traction pull. A rod 58 is secured between the plow unit as at 60 and the end'ofthe extension beam as at 59 to make in effect one rigid beam unit of the two separate beams i and 5d.

Forvarying the depth of 'cut desired the front truck is raised or lowered. The plow unit is tilted'sideways by raising or lowering one wheel, 7 or 8, more than the othergturning the hand wheel20 will raise 'or lower that end of the truck; Working the lever 10 will raise Or lower the other end of said truck.

As' long as the device is pulled forwardly to cause the wheel 28 to rotate, the belt 26 will be driven continuously irrespective of its position. 7

As the conveyer frame is hinged to the plow, the truck 43B is free to rise or lower, being also free to rise or lower relatively to the front truck.

1. Ina device of the kind described, a front truck, a plowing unit drawn from said front truck, an auxiliary truck drawn from said front truck and having a front wheel and a rear swivelled wheel, an endless conveyer positioned between said plowing unit and said auxiliary truck receiving'at one end the earth raised by the plow and discharging said earth at the other'end, and means for actuating said conveyer from the rotation of said'rear swivelled wheel. 7
